【问题描述】:
首先,我在 [blog]:https://www.javadevjournal.com/spring-boot/spring-boot-application-intellij/ 上基于 IntelliJ 创建了一个 Spring Boot 项目。然后,我在其中生成了一个带有 @PostMapping 的控制器和服务。我使用 balana [github]:https://github.com/wso2/balana 来实现 XACML 引擎。
当[博客]:https://docs.wso2.com/display/IS570/Writing+XACML+3+Policies+in+WSO2+Identity+Server+-+7 被遵循时,策略和 xacml 请求被创建为硬编码。当通过 Postman 作为 http post (http://localhost:8080/evaluate) 调用该服务时,xacml 响应在 PERMIT 和 DENY 决定下正常工作。到这里一切正常。
当我想将它发布到 azure web 应用程序时,响应包括 NotApplicable 作为决定。我的政策和要求是否有任何异常或我遗漏了什么?
